Sleep by Your Self

My advice is to first rule out any health (physical or emotional) issues. If there aren't any, then read 'Healthy Sleep Habits, Happy Child' by Dr. Marc Weissbluth to learn how to get him back into his own bed. You say he did it for 2 years so you know he is capable. Start perhaps on a Friday night (weekends - you might not have to work, possible extra time to sleep in case you're up all night) and tell him "Tonight we are going to start a new rule. I am your mother and I want to make sure that you grow up happy and healthy, and part of being healthy means falling asleep in your own bed and staying in your own bed at night. Tonight, once I put you in your bed you will need to sleep in your own bed." Continue with your regular night time routine and tell him once it is time for bed, he is to get in bed and fall asleep and stay there all night. If he gets out, quietly and calmly take him back to bed and tuck him in. No talking, no negotiating, no justifying, no screaming or frustration on your part. If he does this at 2:00 AM and you're dead tired, get up and take him back to his bed. You must be consistent with whatever techniques you use. Be patient; it might take a few days of him being a 'jack in the box' (in his bed, out of his bed) but eventually he will learn that you expect him to stay in bed.

Get him back to his own bed as immediately. Even if he cries a little. It only takes a couple of times of him being with you to get him use to having his way and then it will be harder for you.

I agree with the response that says get him back to his bed immediately every time -- do not play, talk or reinforce him coming to you at all...

Hi G., Have you asked your son why he doesnt want to sleep in his own bed? I know when my oldest was that age he would have nightmares and then was to scared to go back to sleep in his own room. I finally had to buy a small lamp with a low brightage bulb for it so it wasnt to bright. A night light didnt work for my son.(we already had 1 in there). There where also a couple of nights he woke up and was just cold and we didnt know until the next morning. My youngest also had a month of sleep walking. I hope this helped some and good luck to you.

My best advice so you can get some sleep yourself is to not permit him in the bed but if he really wants to be by you let him sleep on the floor nearby. It probably doesn't matter only that one day you may get married or something and you need to have him adjust to his own room then. I know he will then one day wonder how come I can't sleep with mom? Well that is life and he might not like the actual floor and bed might seem better to him. I have two sons and they both went through versions of that. Believe me they themselves don't really want to sleep with you forever, but well now it's so cozy, right? It does stop. Good luck! S.
